Short: AIBB Module for Apollo 1240/50MHz and FastExec
Author: Thomas Krogh
Uploader: u960329@daimi.aau.dk
Type: util/moni
This is a AIBB module made on a A1200 with an Apollo 1240 40Mhz turboboard,
actually it was overclocked to 50MHz (100Mhz int.), this was done simply by
replacing 80 Mhz crystal with a 100 Mhz one, and adding a i486 cpu cooler.
Additionaly I ran : FastExec (with FastINT FastSSP FastEXP options), which
boosted the system extremely much.
I tested my a1240 board against a Blizzard1260 board with Bustest:
Apollo: Blizzard:
Chip(max): 7.1MB/s 4.0MB/s
Fast(max): 65MB/s 40MB/s
PS: if you have a board with an 040 40Mhz, and you want to overclock it,
don't blame my if it one day just doesn't work anymore....
because thats what I have experienced by now, I have been using the 040 at
50MHz for a half year by now, but one week ago it broke down and it could
not startup on 50MHz anymore, so I replaced the crystal back to a 40 Mhz one
again, and it worked fine....
PSS: my experinece tells me that not all 040 40MHz can work on 50Mhz...
